I am looking strictly to be able to buy and sell my own properties. 

Underwriting has strict guidelines on your front end and back end DTI requirements, so you could have perfect credit but be denied because of your DTI.  

I routinely get rents that are significantly over market, and have near zero vacancies.  

Here, there are very strict rule requiring compliance, including legal pub of sale, following 90% of court referee's appraised value rule and then there's the confirmation hearing.

Or would strictly mailing bet better?

My primary reason for asking this question is that I am an out of state investor (from Canada), and my policy is what I call 'Remote REI Strategy', hands-free, no contact with tenants, and I don't want to be called by 1:00am that a bulb is burnt out....strictly no involvement with daily property management and all that come with it.....

We plan to transition strictly into 5+ unit apartment buildings eventually.

I plan to coordinate all of the maintenance/upkeep and have people in place to handle cleaning, snow removal, emergency repairs, routine maintenance, etc. by the time we purchase the building.  

The property is owned by Bank of America, and they have a strict policy that under no circumstances will the water be turned on at the property.My mortgage broker says that it is impossible to get financing on a property without the utilities turned on.
